| Poorly sourced? This was a a report by the "Cour des comptes". https://en.wikipedia.org/wiki/Cour_des_Comptes_(France) Reported on here: https://www.liberation.fr/terre/2012/01/31/au-total-le-nucle... Via Wikipedia https://en.wikipedia.org/wiki/History_of_France%27s_civil_nu... The article explicitly says "overall cost" and "including all expenditures." "Following the Fukushima nuclear accident in 2011, the French government requested that the Court of Accounts prepare a report on the overall cost of both public and private investment in the French nuclear power industry from its beginning, including all expenditures.[225] The report estimates that the industry has cost around 228 billion euros for a yearly production of roughly 400 TWh, with a cumulative production of approximately 11,000 TWh. Among the expenses, the Court of Accounts differentiates €55 billion spent on research since 1950 (equivalent to approximately a billion dollars annually) and €121 billion spent on construction, which includes €96 billion on the 58 reactors." Your quoting estimated future prices does not contradict what has already happened. The new reactors both have higher rated output than what is currently installed and higher capacity factors. Operating costs are small compared to initial investment, and fuel costs are a small part of the operating costs. Let's math the shit out of this! Assuming the 1.5 GW output for the EPR2 that's quoted in Wikipedia and a conservative 90% capacity factor, each of these reactors will produce 1.5 * 24 * 365 * 0.9 = 11826 GWh of electricity per year. 80 year running life makes that 11826 * 80 = 946080 GWh of electricity over the lifetime of the plant. Or 946 TWh. That's 946 Trillion Wh, or 946 Billion kWh. If I can sell these 948 Billion kWh for 1 cent / kWh, that's 948 billion cents or € 9.48 billion so close to the estimated cost of constructing each of these plants. So let's assume an extremely unlikely ~100% cost overrun and operating costs that are the same as originally estimated construction costs and we have 3 cents / kWh. Everything after that is profit, even with 100% cost overruns for construction. Which maybe gives you an idea why, though the French government almost certainly does not like the cost overruns, they don't seem to be nearly as perturbed by them as the anti-nuclear activists. And neither is the UK government. So nobody is going to claim that Hinkley Point C is going well. Nevertheless, the UK is proceeding with Sizewell C, have just selected a site for an additional pair of reactors and have made it policy to quadruple nuclear output. Just like neither the Poles nor the Ukrainians let the problems at Vogtle-3/4 keep them from selecting the Westinghouse AP-1000 for 4 reactors each, with site-prep work having started in both countries earlier this year. |
In 2012 published results for ongoing costs at “The court expects EDF's projected investment programme in existing plant, including post Fukushima safety improvements, will add between 9.5% and 14.5% to generation costs, taking costs to between 37.9 and 54.2 EUR/MWh” (Note that’s annual costs excluding construction and decommissioning.) Your investment number included R&D subsidies that aren’t part of that 47 to 67 EUR/MWh in today’s money. If you wonder how these could be so wildly different it’s because France isn’t just adding up total costs and adjusting for inflation they simply don’t want to admit how large the subsidies have been because it’s so dam expensive.
France nuclear power plants don’t hit 90% capacity factors. If your generate 30% of power from nuclear you can have capacity factors that high but France ran past that and ran into the fundamental issue that people want less power on nights, weekends, and spring/fall when they don’t need heat or AC.
How about some real world numbers. From 61.4 GW of generating capacity In 2022 France produced 282 TWh, in 2023 it hit 320 TWh that’s (282 + 320)/2 / 365 / 24 * 1000 / 61.4 = 56% capacity factor.
Wow that’s low let’s look at some lifetime numbers 72.60% https://en.wikipedia.org/wiki/Belleville_Nuclear_Power_Plant 75% https://en.wikipedia.org/wiki/Blayais_Nuclear_Power_Plant 74% https://en.wikipedia.org/wiki/Cattenom_Nuclear_Power_Plant
Wow your 90% is sure looking crazy optimistic.
“80 year running life” you know France is having troubles keeping a ~40 year old fleet operating, I’m sure they will have zero problems trying to hit 80 years.
